PENCIL SHARPENER.

Application filed June 8,

rllhis invention relates to improvement in pencil sharpeners and particularly to pencil sharpeners (ifomprising a conical pencil-tipeceiving recess formed with a slot in which a blade is mounted, and especially to pencil sharpeners of this type in which the cutter is mounten` in a sheet-metal casing, and is an improvement on the construction shown and described in United States Patent No. 15d-23,- 226, granted .lune 23, 1925. The object of this invention is to so construct the housing that the cutter will be firmly mounted therein to resist the pressure of the pencil when forced into the cutter, and the invention consists .in the construction as hereinafter described and. particularly recited in the claims.

In the accompanying drawings:

Fig. 1 is a side view of a pencil Sharpener constructed in accordance with my invention;

Fig. l is a transverse sectional view of the same; and

Fig. 5 is a front view of the housing with the cutter-frame removed.

In carrying out my invention, I employ a cutter of substantially usual form with a tapered recess 11 for the reception of the end of aspencil to be sharpened. This cutter is formed with a longitudinal slot 12 and attached to the cutter by a screw 13 is a blade 111:, the edge of which extends into the chamber 11. The inner end of the cutter is formed with a tubular bearing 15 and the outer end wi th a stud 16. The bearing 15 and stud 16 are mounted in opposite ends 1T and .lll of a frame, which is struck up from sheet-metal, with side-walls 19 and 20, the bottom 2l, side-walls 19 and 2O and endpiece 1T being preferably formed from a single piece of metal, the end 1S being separately fornutd and connected to the frame by side-lugs Q2 and bottom-lugs 25 forming an integral structure, and the frame forming a receptacle to catch shavings` The housing for the cutter, like the housing of the patent above referred to, is formed from a. strip of sheet-metal bent into U-shape, with the edges 241 turned outward to form flanges by which the housing may be secured to a support. Extending transversely across 2 is a front view of the same, 3 is a vertical sectional view of the 1926. Serial No. 114,381.

the housing is a floor forming a chamber for the reception of the cutting mechanism, the floor being formed at the center with a downwardly-extending U-shaped extension 26 for the purpose as will hereinafter appear, and at its forward edge with upwardly-extending lips 27.

Secured to the outer end of the stud 16 a crank-handle 28.

Instead of entering the cutter from the front of the housing, as in the patent above referred to, it is entered from the rear, the depression 26 in the bottom forming a clearance for the handle 28, and the lips 2i' forniing stops to prevent the further forward movement of the cutter.

The device is used in the usual way by inserting the end of a pencil into the chamber 11 and holding it while the crank is turned and the cutter' revolved, but in this construction, the pressure ot the pencil into the cutter tends to force the cutter forward against the lips 27, which form stops to prevent further forward movement, so that it is impossible to force thecutter out of the housing during the sharpening operation.

I thus provide without increased cost of manufacture, a pencil Sharpener in which the cutter is firmly mounted in the housing.

I claim:

1. A pencil Sharpener, comprising a cutter, a frame in which the cutter is mounted, said cutter provided with a crank-handle, and a housing formed with a transverse floor, the central portion of the floor outwardly bowed and the forward edge of the floor formed with lips against which the cutterframe bears.

2. A pencil sharpener, comprising a cutter-frame, a cutter mounted in the ends of the said frame and provided with a crankhandle, a housing formed from a strip of sheet-metal bent into U-shape and provided with a transverse floor upon which the cutter-frame rests, said floor formed with a centrally-arranged U-shaped bend and at its rear edge with upwardly-extending lips forming stops for the cutter-frame, whereby the cutter-frame is entered from the forward end, the central depression in the. floor providing clearance space for the said handle.

In testimony whereof, I have signed this specification.
